+#### Cyclosm data dependencies
+
+##### Shp
+
+Download the 2 following zip files, unzip them, and place them in the `pbf/shp` folder. They are mounted as volume in the docker-compose.yml.
+
+- http://osmdata.openstreetmap.de/download/simplified-land-polygons-complete-3857.zip
+- http://osmdata.openstreetmap.de/download/land-polygons-split-3857.zip
+
+Also, rename them as in the zip file, so simplified-land-polygons-complete-3857.shp and land-polygons-split-3857.shp.
+
+
+##### Contour lines
+
+Download the geopackage from http://opendata.champs-libres.be/beautiful-contour-belgium.zip, convert it to shp and place it into the pbf/shp folder under the name "contours.shp". It will be mounted as written in the `docker-compose.yml` file.
+
+The shp is imported using `shp2pgsql` in the import step, assuming EPSG:31370 as the input shp CRS.
+
+#### Hillshade
+
+Download the hillshade at http://opendata.champs-libres.be/hillshade_belgium_EPSG3857.zip and place the tif file in the pdf folder, as mounted in the `docker-compose.yml` file.
+
+
 #### Do an import
 
 Download a pbf and a poly file of your choice on https://download.geofabrik.de and put it in the `pbf` folder. Change the lines of the pbf and poly paths in the volumes in the `docker-compose.yml` file
